This high-performance version of the BMW 3-Series came from the factory equipped with a better engine, improved braking, and a sleeker body style—and this enhanced BMW deserves an Air Lift air suspension kit to make it that much more capable. Whether you have the sedan, the coupe, or the convertible, Air Lift can outfit your BMW with the right kit for your lifestyle. The rear kit also places a compact double-bellows air spring in the original factory coil location, uniting it with a 30-level damping adjustable, monotube, threaded body shock with independent height adjustment. The proprietary lower control arms and toe links have a high-gloss, black powder-coating, and are complemented by lightweight, bright-red anodized aluminum spring spacers. This kit includes both ¼” and 3/8” PTC fittings. As the leader in air suspension products for over 60 years, Air Lift is committed to delivering quality parts that last. To ensure longevity for the customer, the key suspension components have been tested on a durability rig for over one million cycles, which equates to 100,000 miles. With a one-year, unlimited-mileage warranty—not to mention the Air Lift Performance reputation for great customer service and technical support— you can purchase this kit with peace of mind. Ditch those coils and get to a new level of low.
